我已经为这个问题苦苦挣扎了很长时间。它发生在全新安装 Windows 10 操作系统后。基本上，在播放 HTML5 视频时，音频和视频逐渐不同步。视频也相当不连贯。如果我强制使用 Flash Player，则不会发生这种情况，因此我确信这是一个软件问题。
我尝试打开所有处理硬件视频解码的 chrome://flags，也尝试过将它们全部关闭，但都没有成功。我以为可能是我的 5.1 接收器和/或电视的问题，但事实并非如此，因为 Flash 播放器运行正常（就视频/音频不同步而言，但 Flash 播放器还有其他问题，例如播放 YouTube 视频时会播放隐藏广告，但这可能是由于强制 Flash 播放器破解造成的）。
我也尝试了 Canary，但也有同样的问题。Firefox 和 IE 也有同样的问题，所以这可能是 webkit 的问题？
电视以 4K 分辨率运行，我尝试了多种不同的刷新率。刷新率似乎会改变不同步所需的时间。我还尝试过更改音频质量，在视频播放过程中更改音频质量时，它会正确重新同步，但最终又会不同步。
我试图改变音频缓冲区，但它似乎只会导致 Chrome 崩溃，而且似乎该修复程序已经过时了几年。
这不可能是我的机器。说实话，它简直就是一头野兽，我已将配置发布在下面。我已将所有驱动程序更新为制造商提供的驱动程序。Chrome 版本 58.0.3029.110；当然是 64 位。

答案1
可从网上商店的 chrome 扩展程序中获得。该扩展程序可纠正使用 flash 播放 html5 视频的问题。问题出现在 flash 尝试覆盖 html5 的内存空间时。HTML5 Flash Warning Fix for YouTube™ 是扩展程序名称。它对我有用，我已经使用了一段时间。希望它对你有用。祝你好运 Gordon McIntosh
